Camera Body Lens Adapter Anti-Vibration Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In camera systems with multiple units having anti-vibration functions, independent anti-vibration operations can compete, leading to deteriorated overall performance, and assigning a specific unit as the host may not optimize anti-vibration performance due to varying system configurations.
Innovation Solution
A processing device determines whether a lens unit mounted via a lens adapter with anti-vibration function has anti-vibration capabilities and coordinates arithmetic operations accordingly, allowing the lens adapter or camera body to perform coordinative anti-vibration based on the determination, thereby optimizing anti-vibration performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple units with anti-vibration functions perform operations independently, then each unit can operate autonomously, but the overall anti-vibration performance deteriorates due to competing operations
Solution Approach 1:
The patent merges the anti-vibration operations of multiple units (lens unit, lens adapter, camera body) into a coordinated system. The host unit performs coordinative arithmetic operations that consider vibration data from all units, ensuring they work together rather than compete, thus maintaining autonomous operation capability while improving overall performance.
Solution Approach 2:
The patent introduces a host unit as an intermediary that mediates between multiple anti-vibration units. The host receives vibration data from all units, performs coordinative arithmetic operations, and distributes control signals appropriately, enabling autonomous operation while preventing performance deterioration through centralized coordination.
2Device complexity
If a specific unit is uniformly assigned as host, then the control structure is simplified, but optimum anti-vibration performance cannot be exhibited depending on system configuration
Solution Approach 1:
The patent implements dynamic host determination where the host unit is not fixed but determined based on real-time system conditions and configuration. The processing device evaluates which unit (lens adapter or camera body) should serve as host based on the specific system setup, allowing the control structure to adapt dynamically rather than being statically assigned, thus optimizing performance while maintaining manageable complexity.
3Reliability
If the lens adapter performs coordinative arithmetic operation, then anti-vibration performance is optimized, but communication delays and data transmission loads increase
Solution Approach 1:
The lens adapter serves as an intermediary that collects vibration data from the lens unit and coordinates with the camera body. By positioning the lens adapter as the host unit in certain configurations, the patent reduces the communication path length and data transmission load compared to having the camera body perform all coordinative operations, thus optimizing anti-vibration performance while minimizing communication delays.

AI summary
Provided is a processing device including a determination unit that determines, in a case in which a lens unit is mounted on a camera body via a lens adapter having an anti-vibration function of suppressing blur in a captured image, whether the lens unit has the anti-vibration function. The determination unit further causes the lens adapter to perform a coordinative arithmetic operation for anti-vibration on the basis of determination that the lens unit has the anti-vibration function.
